If that is the case are there any features on the Pen-F which could find their way to the E-M1 via firmware updates?

I suspect not. The Pen F has a new 20 megapixel sensor and a new TruePic image processor. One key new features is the image profiler and it wouldn't surprise me if that was specific to the new processor. The Pen F doesn't have phase detect AF, which remains exclusive to the E-M1.
